Apple slid into a bear market Wednesday, down 20% from its October peak.

The tech giant in August became the first US company with a $1 trillion valuation. It saw its market value top out at $1.12 trillion in early October, before a stock-market sell-off ravaged the tech sector. Apple was not immune.

In November, Apple reported underwhelming iPhone sales and said that its holiday quarter will be on the low end of expectations. It also said that it would stop reporting unit sales for iPhones, iPads, and Macs.

But that was just the start of the recent worries for Apple shareholders. Earlier this week, a handful of Apple suppliers cut their outlooks, suggesting weaker smartphone demand ahead.

On Monday, Lumentum, the main supplier of the Face ID technology in Apple’s latest generation of iPhones, cut its outlookafter one of its biggest customers reduced its shipment request. Then, On Tuesday, Qorvo, iPhone radio-frequency chip supplier lowered its guidance due to a drop in demand for flagship smartphones. A handful of other iPhone suppliers, such as screen maker Japan Display and British chipmaker IQE Plc, also slashed their forecasts this week. None of the companies specifically named Apple as the culprit.

And analysts up and down Wall Street have been downgrading the stock and cutting their price targets in response to the recent developments.

“We see growing risk of even softer iPhone unit demand, with downside in China, India and other emerging markets, where Apple may need to start considering lower price points,” Guggenheim analyst Mark Cihra said in a note sent out to clients on Wednesday. He downgraded Apple to “neutral” and removed his prior $245 price target.
